So... I have now realized that I have a problem casting heavier flies. It appears that I can cast dry flies or green weenies etc well but when trying to cast a wolly bugger or something heavier I am having issues.

I'm 5-10 minutes north of you. If you want to have someone take a look at your casting / see if I can get you on the right path, shoot me a PM. We can go above the dam on Stony and chuck a few casts after work one evening.
